Title: Semiconductor wafer dividing apparatus
Inventor: ICHIKAWA TOSHIHARU
IPC: B28D5/00
Filed: 1986-06-12
Abstract: PURPOSE:To prevent remaining of scraps of semiconductors, which are yielded in dividing on the surfaces of the semiconductor elements, and the damage of the surfaces of the semiconductor elements, by covering both surfaces of a semiconductor wafer with flexible sheets, inserting a vacuum sucking needle between the flexible sheets, and evacuating the air in the inside so as to form a vacuum state in the dividing work. CONSTITUTION:A semiconductor wafer 11 to be divided and the tip of a vacuum sucking needle 14 are held with vinyl chloride sheets 12 and 13. The peripheral parts of the sheets 12 and 13 are fixed to a thin rubber plate 16 with a fixing plate 15. Then air is sucked through the sucking needle 14 so as to form i a vacuum state. Then, the sheets 12 and 13 are closely contacted with both surfaces of the wafer 11. Under this state, a manual roller 17 is moved, and the wafer 11 is divided along scribing lines. Then, semiconductor scraps are yielded. Since the sheets 12 and 13 are closely contacted with the surfaces of the wafer, the semiconductor scraps do not damage the surfaces of the semiconductor elements.

Title: Digital trunk circuit
Inventor: KIKUCHI SHIROU
IPC: H04Q1/457
Filed: 1977-11-15
Abstract: PURPOSE:To obtain a circuit which will not complicate a conversion processing program and is protected from circuit noises, by varying the discrete value of the multiplier of a digital filter supplied with a circuit state signal corresponding to the connection state of a call. CONSTITUTION:A signal from each circuit is applied to digital filter 3 after being digitalized and multiplicated by multiplication circuit 2. For example, when circuit 1-1 is free, the coefficient value such as (alpha1) of register 6 is selected for filter 3, and low comparative level (beta1) of register 9 is for comparator 4. Once the circuit is acquired, the output of filter 3 changes into its munimum-level output at a time constant equivalent to (alpha1), and the output of comparator 4 changes from ''1'' into ''0'' when the filter output becomes equal to (beta1). At this time, the change is identified as the reception of a starting signal, and registers 6 and 9 are changed with registers 7 and 10 respectively so as to set the coefficient value of the filter to (alpha2) and the comparative level to (beta2).

Filed: 1985-06-24
Abstract: PURPOSE:To grow and form a high quality semiconductor crystal, by forming a semiconductor layer, which constitutes a second semiconductor that is contacted with a third semiconductor, with a semiconductor material, whose lattice constant is smaller than the lattice constant of the third semiconductor. CONSTITUTION:A semiconductor device is formed by sequentially laminating a buffer layer 12 and a gallium arsenide crystal 13 on a silicon substrate 11 having a surface orientation of [100]. The buffer layer 13 comprises 10 SiGe mixed crystal layers, with their composition ratios being increased stepwise by every 0.1. In this semiconductor device, it is necessary that the thickness of each SiGe layer constituting the buffer layer 12 is set at a value larger than the critical thickness, which can be alleviated in dislocation newly caused by the lattice misalignment between the layers. In this case, the thickness is all set at about 0.2mum. Thus problems such as cracking and peeling can be avoided, and the device having excellent crystalline property is obtained.

Title: Digital servo system
Inventor: OKITA IWAO
IPC: G05B11/36
Filed: 1980-10-04
Abstract: PURPOSE:To increase not only the stability but the linearity and the responsiveness for a digital servo system, by inserting a phase compensating digital filter into a servo loop. CONSTITUTION:When a shift command pulse is supplied to a position counter 1, the output of the counter 1 is compared with the output of a speed counter 8 through an error arithmetic device 2. With this difference of outputs, a pulse duration modulating circuit 3 works. Thus the difference of outputs is converted into the current by a power amplifier 4. Then a servomotor 5 turns, and the output of a pulse encoder 6 is converted into the positive and negative shift pulses by a pulse decoder 7. The counter 1 performs a count-up or count-down action according to the positive or negative state of the shift command pulse. The gain of a comparatively high frequency region that affects the stability of system is suppressed; while the gain of a comparatively low frequency region that has no contribution to the stability is increased. Then a speed loop phase compensating digital filter 9 is connected with a current loop phase compensating digital filter 10. Thus both the linearity and the responsiveness are improved.

Title: Solenoid valve driving device
Inventor: KANEKO MITSURU
IPC: F16K31/06
Filed: 1984-07-04
Abstract: PURPOSE:To reduce a voltage drop at the time of rectification by rectifying alternating voltage generated in a secondary coil by switch operation of a transistor. CONSTITUTION:When an output of a drive circuit 3 of a switching element 2 is at low potential, alternating voltage is generated in a secondary coil of a pulse transformer 1, so that only when emitter of a transistor 9 is higher than the base potential, a base current flows through a resistance 8 to turn on the transistor 9. Thus, a condenser 6 is charged to supply voltage to a solenoid valve 7. As enough voltage to spare can be supplied to the solenoid valve 7, an electric current flowing through a primary coil of the pulse transformer 1 can be reduced.

Title: Optical head device
Inventor: TANAKA MASATO
IPC: G11B7/125
Filed: 1989-05-31
Abstract: PURPOSE:To prevent an optical axis to a recording medium from being deviated and a spot position from being changed by detecting the temperature of a semiconductor laser, controlling an electric current flowing to a temperature control element by means of a control circuit and maintaining the temperature of the semiconductor laser to be always constant. CONSTITUTION:The temperature of the semiconductor laser 1 is always detected by a temperature sensor 2. A temperature signal detected by the temperature sensor 2 is inputted to a temperature control circuit 3 and the electric current flowing to the temperature control element 4 is controlled by the temperature control circuit 3 based on the inputted temperature signal. As the result, the temperature of the semiconductor laser 1 is maintained to be always constant. Thus, laser light whose wavelength is constant is outputted from the semiconductor laser 1 and condensed on the recording medium 9 through a collimator lens 5, a beam shaping prism 6, a beam splitter 7 and an objective lens 8. Since the wavelength of the laser light outputted by the semiconductor laser 1 is not changed by the change of the circumferential temperature, the failure that the optical axis is deviated or the spot position is changed is eliminated.
